4The p-resent invention relates to side door constructions.

More particularly the present invention relates to the doors of railwayhouse cars of the type commonly called automobile cars. House cars forthe shipment of automobiles or other bulky lading require a particularlywide door opening. Cars of this sort are commonly provided, in additionto the usual sliding door, with a secondary or supplementary door, whichsecond or supplementary door is slidably movable to provide a dooropening of extraordinary width, but which may be stationarily held whena door opening of such extraordinary width is not required. In order tolock said supplementary door in its closed position, it is common toprovide a movable door jamb which may be secured tov said supplementarydoor or may move independently of said supplementary door. In eithercase said jamb should be capable of movement longitudinally; of the carand should have means for locking same in position. Certain types ofdoor jamb for said supplementary doors have provided means lfor holdinga'nailing strip for theY securing of grain doors such as are usedinlining the car when the car is used for the purpose of' carrying grainor other finely divided lading. It is common to provide the amb of thesupplementar door with latchin members for latching t e jamb in doorclosmg position.

An object of the present invention is to provide a constructioninvolving a supplementarA door and a door amb therefor, which ]ambrequires a minimum of kinds of fittings.

A further object is to provide a door jamb involving relatively simpleparts which include castings at the top andbottom of said j amb, whichcastings may be identical, theren by simplifying the matter of stockingrepair parts.

V A further object is to provide a door `jamb having socket members atits top and bottom, which socket members provide housings for latchin'gmembers and which house the two extremities of a wood filler post.

A further object is to provide a door amb of great strength, which willafford protection to the means lfor operating the latches above referredto.

A further object is to provide a socket member which may be used eitherat the top 1927. erm No. 207,877. i

post arrangement The numeral 10 indicates the side sill and the numeral11 indicates the side plate of a railway box car. The numeral 12indicates init-s entirety a movable door jamb which in the constructionillustrated is la metal jamb. Said jamb is secured to the supplementarydoor 13. VSaid jamb is adapted to be moved with a movement oftranslation longitudinalof the car along with said supplementary.

l diner 13. Figure 1 illustrates the jamb 12 in its home or door closingposition. In this polsition certain latching mechanism cooperf ativelyassociated with the jamb 12 engages with detent members stationarilymounted upon the side sill and side plate of the cal.

, over a plain angle and bers 14 and 15 is provided With overhangingshoulders 17 on the'tvvo sides thereof, which cooperate With extendingportions to be ref terred to hereinafter, rigidly secured tothe j amb12, whereby when said j amb 12 is in its home or door closing position,said jamb' acts as a tie member to prevent spreading between the sidesill 10 and the side plate 11. 'lhe detent 14 is provided on its uppersurface with the recess 13 providing a square shoulder i 19, and thedetent member 15 is provided with the recess 2O providing the squareshoulder 21, which shoulders 19 and 21 operate with latching members,tobe referred to hereinu alter, to hold the jamb-12 in its home or doorclosing position. y

The jamb 12 preferably is embodied in a rolled shape 22, the crosssection ot which is illustrated in Figure 3. lt will be noted that therolled shape 22 is a F-bar, the Web 23 oi' which is disposedtransversely of the car 'and the flange 24` oit Which is disposedlongitudi nally oit the car. The other lane 25 may take the form of areinforcing bul y25. rlhe Z-bar 22 has an improved section modulus lthereby permits the use of a relatively light Weight shape, whichrelatively light shape has the advantages thatv fabrication andhandling'. are simplified. its will be pointed out hereinafter, theflange or bulb 25 has the further advantage that. it protects theoperating bar ot the latching mechanism ont `the car from damage due toshifting lading. rl`he extremity of the flange 24 of the rolled shape22'is inwardly bent to provide a lip 26, which providesv a door guidetor the main door' 2K7.

Disposed within the reentrant angle ot the rolled shape 22 is the Woodfiller post 23, 'which filler post is adaptd to have a nailin strip 28Asecured thereto.l `\\lt Will be noted that the rolled shape`22 presentsa reentrant angle toward the interior ot the car and toward the openingcontrolledby the main door 27 V(see Figure 8), this construction havingthe advantage that the filler post 28 and nailing strip 23A may bechamtered oil', as indicated in Figure 3 by the-line 28B, to provide amaximum of space to permit the clearance of hubs and tenders ofautomobiles inserted diagonally into the house car.

Disposed at the top and bottom ot the jamb 12 are the housings or socketnimnbers 29-29, which are identical and in a preferred Leefbaarembodiment of the present invention take the form of castings. The Woodfiller post 23 is gained into said castings 29-29 at the two ends ot'said strip 28. Figures 4, 6, 7 and 9 show one of the castings 29 in theposition it assumes when used at the bottom ot' the jamb 12. lt Will benoted` that said casting 29 includes a socket portion 3 0 in -Which thefiller post 28 is disposed, said liller post 28 having a reduced endlportion 31 tor this purpose. @ne Wall 32 of the casting 29 is providedWith a. pair of holes 33-33 t'or the reception of rivets or bolts torsecuring said Wall 32 to the web ot the rolled shape 22. Each ot theWalls 34-34 adjacent to the Wall 32 is provided with the hole 35. ln thecase of a casting 29' used at the bottom ot the jamb 12, one of saidholes 35 is used tor receiving a rivet or bolt Jfor securing thecorresponding vfall tothe flange 24 ot the Z-bar 22. 1n the case ot acasting used at the top of the jamb 12, the other of said holes 35 isused 'for securing the corresponding Wall 34 to the iian'ge 24 oi thelZ-bar 22.

llrom an inspection ot' Figures 2, 3, 4, 5, 6 and 7 it will be notedthat the extremity of the casting 29 spaced. from the Walls 32 or 34-34is provided With the pair of lip portions 36, which extend toward oneanother .and are adapted to -have overlapping relationship with theshoulders 17-12 ot' the detent members 14 and. 15 at the bottom and topol the car.

-lteterring to the sectional view illustrated in Figure 7, the innerconformation ot each sidewall 34 is illustrated. rllhe two side Walls 34are identical, -so that a description of one of said side Walls willsutiles-for both. lt Will be noted that the inner surface of each wall34 is provided With projections forming a pair of sockets 37 and 38,which sockets providebcaring's for latching members 39 and 40 disposed,respectively, at the bottom and top ot the jamb 12. l lt Will be notedthat the-socket portions 37 and 38 have restricted entrances 41 and 42,respectively. yl`he trunnions 43 and 44 oi the latch members 39 and 40,respectively, are provided With fiat faces, whereby said trunnions 43and 44 may be admitted through ,said entrances 4.1 and 42, respectively,when the latches are turned at predetermined angles. The flat laces ofthe trunnions 43 are indicated by the numerals Ll-5--45- A dat tace onthe trunnion 44 is indicated by the numeral 46;, Said flat faces 4.5-45and 4G are so disposed upon thc trunnions 43 and 44, respectively, thatsaid trunnions'can be removed 'from their corresponding socket portions3T and 33 only when the latches 39 and fi-(l are disposed in an angularposition which they cannot assume u'ith the door janib and the letents14 and 15 in normal positions within the car and with the liller post 23in position.

rlhc latches 39 and 40 lare connected to one lSO another by means of thelatch operating bar 47. The details of the bar 47 need not bedescribedhere/in, the subject matter of a similar latch operating bar beingdescribed and claimed in the Tobin and Darrow Patent No. 1,533,621,issued April 14, 1925. It will be sulicient to state that the bar 47causes the latching members 39 and 40 to move in unison, whereby thejamb 12 will either be in latched conditon at both top and bottom, or inunlatched condition at both top and bottom,

'litii particular reference to steel door construction, attention isdirected to the reinforcing'plate 48 secured along one edge to the door13 by means of a row of rivets 49 and along its other edge to the web ofthe Z-bar 22 by means of a row of rivets 50. Said rein- Jforcing plate48 not only strengthens the construction, but prevents lading fromgetting into the'corner between the door 13 and the web of the Z-bar 22.The front edge of they .door 13 and the flange 24 are secured togethelby means of the row of rivets 5l. y The rolled shape 22, the reinforcingplate 48 'and the front edge portion of the door 13 thereby form atrusswork which effectually protects the door jamb against twisting. Thefiller post 28 is secured to the rolled shape 22 by means of bolts 52and 53.

Though the tiller post 2 8 maybe a permanent part of the j amb, it maybe desired to remove said iller-post in case said filler post becomesinjured and to insert a new filler post. In order to remove said fillerpost 28 without requiring the dismantling of thc castings 29-29 from theZ-bar22, or removing the j amb proper from the door to which it isriveted, the filler post 28 may be cut transversely, as indicated by thenumeral 49. After removal of the holding bolts, the two eX- tremities ofthe liller post 28 maybe readily removed and other sections may bemounted in place, the bolts being reinserted to secure the two sectionsof said filler post in rigid relationship with the Z-bar 22.

As appears from the drawings, each housing or socket member 29 is openfrom top to'` bottom, this construction having the decided advantagethat in case it should be necessary to remove the latch 39 at the bottomof the jainb and replace same with another,f"the change can be madeveryvreadily without taking the car out of service. Though the latchesare ordinarily quite sturdy, breakage ot the lower latch may occur ifsaid latch is subjected to very roughv treatment. To

change a lower latch 39, the filler post may' be removed in a mannerreferred to above, and the jamb may be moved to a position free of thedetent'l4, 'such for example as the positon illustrated in' Figure 9.
